A rate comparison tool for online sellers
Small stores often guess at postage and lose margin on heavy or bulky orders. A ShipmentCost calculator could let a seller enter package size, weight, origin and destination, then view carrier options side by side. The first offer would be a simple comparison table with delivery speed and total price, plus a saved-profile feature for repeat products. The name fits because it states the number a seller needs before setting prices, free-shipping thresholds or handling fees, and it stays plain enough for a storefront help page.
